Abstract

The invention discloses an environment-friendly emulsion explosive. In order to solve the problems that existing emulsion explosives are high in production cost, low in use safety, poor in explosive combustion performance, environmental protection effect and energy-saving effect, poor in explosive quality stability and frost resistance and low in storage stability, according to the following scheme, the explosive is prepared from, by weight, 60-80 parts of an aqueous-phase solution, 10-16 parts of a hydrocarbon fuel, 1-4 parts of a composite emulsifier, 2-5 parts of a density regulator, 1-3 parts of a sensitizer, 1-2 parts of a foaming accelerator and 12-17 parts of water. According to the environment-friendly emulsion explosive, the sources of explosive combustion substances are wide, theproduction cost is reduced, and the safety of the explosive is enhanced; the combustion performance of the explosive is optimized, and the energy and the consumption speed are increased, so that theenvironmental protection performance and the energy-saving performance are improved; the quality stability and frost resistance of the explosive are excellent, and a spontaneous combustion phenomenonin a sulfur-containing gun hole is effectively prevented; the storage stability and the optimized explosive performance are excellent.

Description

technical field [0001] The invention relates to the field of explosives, in particular to an environment-friendly emulsion explosive. Background technique [0002] Environmentally friendly emulsion explosive is a water-in-oil latex explosive, which is prepared by chemical processing methods such as water phase solution, hydrocarbon fuel, compound emulsifier, density regulator, sensitizer and foaming accelerator. It is more common in blasting and other places. [0003] The high cost of burning substances in the explosion of the existing emulsion explosives leads to low production efficiency of the emulsion explosives and poor safety of the explosives, poor combustion performance of the explosives and low energy and low burning rate, which affects environmental protection and energy saving, and the stability and quality of the explosives. Poor frost resistance, prone to spontaneous combustion when used in sulfur-containing blastholes, and poor storage stability and optimized ...
